Beginning at 9PM PST UTC/GMT -8 hours on Friday 8/18/06 our engineers will be installing a new UPS this will cause a five minute
outage while the servers are powered down and back up. After the UPS
change our engineers will be installing tipping point IPS
and windows server updates on all of the shared hosting servers. These
updates will cause brief outages or packet loss during the reboots and
update installation.
